基于软件模拟的调湿材料调湿性能对比
|
摘要
建立调湿墙体与室内外空气热湿耦合传递模型,在9:00—17:00室内出现散湿源、散热源的条件下,利用COMSOL Multiphysics软件模拟5种调湿墙体(编号为1～5,仅调湿材料不同)的热湿传递,以调湿墙体内壁面湿流密度的绝对值作为评价指标,筛选调湿性能最优的调湿材料。在5种调湿墙体中,调湿墙体4(调湿材料组成为:石膏质量分数75%,陶粒质量分数25%)内壁面湿流密度的绝对值大于其他4种调湿墙体,调湿墙体4采用的调试材料的调湿性能最优。
The heat and moisture coupling transfer model between the humidity control wall and the indoor air is established. Under the condition of the wet source and the heat source in the room from 9: 00 to 17: 00,the heat and moisture transfer of five humidity control walls( numbered 1 to 5,only humidity control materials are different) are simulated and calculated by COMSOL Multiphysics software. The absolute value of the wet flow density on the internal surface of the humidity control wall is used as the evaluation index to screen the humidity control material with the best humidity control performance. In the five kinds of humidity control walls,the absolute value of the wet flow density on the internal surface of the humidity control wall 4( the composition of the humidity control material is : gypsum mass fraction of 75%,and ceramsite mass fraction of 25%) is greater than that of the other four humidity control walls. The humidity control performance of the humidity control material adopted by the humidity control wall 4 is optimal.
